The circumference of the seating area has a surrounding seam, and the seating area comprises the shapeable seat section and the backseat section. The space between the surrounding seam and the hemming is connected by a stretchy or stretchable element to create the mounting structure. This invention is a seating area that is shapeable to form a seat section and a backrest section. It contours to the hip and does not create any tightening sensation.

BACKGROUND OF THE INVENTION Field of the Invention

This invention is to a type of chair surface for folding chairs.Specifically, it is a chair surface with a shapeable seating area thatshapes into a seat section and a backrest section and is mounted to thesupport section of the folding frame by a stretchable element.

Technical Background

Stretchable (“stretchy”) chair surfaces are a recent development overthe past few years. The surface has a simple structure and a chic designand has become very popular. It is particularly suitable for use aschair surface for leisure chairs. Chinese patent application number2012207061144 shows one type of stretchable cord chair surface. Thestructure of the chair surface includes the hemming as well as a seatingarea mounted to the support section of the chair surface. The seatingarea includes a seat and a backrest. The backrest is made of braided,stretchy cords. In the absence of weight, the chair surface is tight andsmooth. That chair surface has both a novel and chic design. Itrevolutionizes the traditional Oxford fabric look of chair surfaces. Itfeatures a pleasurable sitting experience and is stretchable. However,the small diameter of stretchy cords creates a tightening (“tensed”)sensation on the hip. In addition, the weaving process of the chairsurface involves complex workmanship. In view of this, the manufacturerhas made certain improvements. Chinese patent application number2014203515772 shows a type of stretchy strap chair surface. By replacingstretchy cords with stretchy straps, it reduces the complexity of theweaving process. Such proposal, however, still requires that parts ofthe seating section and the hemming to be sewn together such that when aperson sits on it, the hip and the seat create obvious movements andalso a tightening sensation. Hence, how to improve on this deficiency isa goal of this invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

With reference to FIG. 1 and FIG. 2, a rounded-shape folding chair isprovided which includes a folding frame 1 and a main chair surface 2.Folding frame 1 includes a support section 11 for suspending or mountingthe main chair surface 2. In this embodiment, the support section 11 isa circular configuration. The support section 11 may be in geometric orother shapes, such as triangular, trapezoid, or pear shapes. None ofthese shapes will affect the configuration of the main chair surface.The main chair surface 2 is mounted to the chair surface support section11 by the hemming 21 on its circumference to create a seating area.

The main chair surface 2 includes the hemming 21 and the seating area.The circumference of the seating area has a surrounding seam 22. Theseating area comprises the shapeable seat section 23 and backrestsection 24. The space between the surrounding seam 22 and the hemming 21is connected via a stretchy element to create the stretchy mountingstructure.

The seating area which includes the seat section 23 and the backrestsection 24 is made of processed nylon mesh or Oxford fabric. The hemming21 and the surrounding seam 22 are made of processed Oxford fabric. Theshapeable seating area, which is made of processed nylon mesh, featuresgood breathability, a feature particularly suitable for summer usage.

The inside edges of the hemming 21 and the outside edges of thesurrounding seam 22 have similar configurations. The preferred designfor the inside edges of the hemming 21 and the outside edges of thesurrounding seam 22 is a round-shaped design, which features even andbalanced weight support. There are three types of configuration for thestretchy element that connects the hemming 21 and the surrounding seam22: first, stretchy cord; second, stretchy strap; third, stretchyfabric.

In FIG. 1 and FIG. 2, the connection illustrated is a stretchy cord 25configuration. Cord eyes 210 are evenly distributed along the area nearthe inside edges of the hemming 21. Cord buckles 220 are sewn evenly tothe area close to the outside edges of the surrounding seam. Thestretchy cord 25 is woven through all the cord eyes 210 and cord buckles220, and the two ends of the cord are joined together. The meanderingstretchy cord 25 creates a suspended seating area, which means thematerial of the seating area itself is not stretchy. It leverages thesuspending stretchy cord 25 to create the stretchy effect.

There is a need to specify here that the cord eyes 210 on the hemming 21and the cord buckles 220 on the surrounding seam 22 can be either cordeyes or cord buckles. They are interchangeable. Their purpose is toallow the meandering stretchy cord to pass through, and to create anappealing aesthetic appearance.

In FIG. 3, the connection illustrated is a stretchy strap 26configuration. The stretchy strap 26 forms a radial shape and spreadsevenly across the area between the hemming 21 and the surrounding seam22. One end of it is sewn to the inside edges of the hemming 21 and theother end to the outside edges of the surrounding seam 22. The evennesscreates the suspending utility for the seating area.

In FIG. 4 and FIG. 5, the connection illustrated is a stretchy fabric 27configuration. The stretchy fabric 27 is cut or formed into a roundshape. Alternatively, it may be called the effective circle of thestretchy fabric 27. Its inside edges and the outside edges of thesurrounding seam 22 are sewn together. Its outside edges and the insideedges of the hemming 21 are sewn together. The seating area is mountedto the hemming 21 via the stretchy fabric 27 to create a uniqueconfiguration. In FIG. 4, the illustration shows the hemming 21 with aninner circular shape inside and an outer triangular shape. This designoffers the support needed for the triangular support section 11. Or asillustrated in FIG. 5, the hemming 21 and the surrounding seam 22 mayboth be provided in triangular shapes, which correspond to thetriangular support section 11. This design allows the backrest 24 toextend upward, providing more supporting surface area for the back.

In summary of the above, the inside edges of the hemming 21 and theoutside edges of the surrounding seam 22 may adopt similar kinds oftriangular shapes, or pentagonal shapes, etc. to create aestheticallypleasing designs to enrich the product portfolio and to provide optionsfor different personalities. All of the above variations are under theprotection of this application.
